The article introduces a new type of modular houses that focus on being environmentally friendly and efficient. The researchers looked at different types of modular buildings and materials, and decided to use Prefabricated Finished Volumetric Concrete Construction (PFVCC) for their houses. They then built prototypes to test their mechanical efficiency, energy saving capabilities, and the construction process. The goal was to create houses that are easy to build, energy-efficient, and can be easily taken apart and rebuilt in the future.
